Hello,
I borrowed a RigExpert analyzer and was able to take measurements that
folks were asking for without AM station overload. I also built the K9YC
160m choke (18 turns of RG58 on a type 31 2.4" toroid). That choke is at
the feed point of the vertical. The analyzer was connected directly after
the choke.
I have a collection of data and typed it into Excel but I can summarize
here.
The values are Freq, SWR, R, X, Z
1810 2.1
1820 1.9 29.1 -14.3 32.4
1840 1.8 31.0 -5.7 31.5
1850 1.7 32.0 -1.3 32.1
1860 1.5 33.0 3.6 33.2
1880 1.6 35.3 13.0 37.6
1900 1.8 38.0 22.9 44.4
1920 2.1
1940 2.5
1960 3.0
1990 3.9
I still only have the 30 x 42' radials attached but can add about 5 x 100'
more radials (in a non uniform layout) if that might help.
Fair, bad, really bad, horrible, hopeless? Any advice is appreciated.
73,
Todd - NR7RR
